Has the ath0 device been created?

run iwconfig with no arguments.  If you do not see ath0 then the device
is not being created properly.

I also have my athX device as part of a bridge, which I needed to
specify in the hostapd.conf.

Unless you are absolutely sure you need it, there is no reason to use
TKIP.  This has nothing to do with your problem, just a security tip.
